** Description changed:
I need to run nested Ubuntu 12.04 and 14.04 containers on 16.04 hosts,
and have noticed that the cgroups-mount script for mounting the cgroups
inside the containers has stopped working. This is because systemd now
comounts multiple controllers on a single hierarchy, which prevents
mounting them individually inside the container.
+
+ =========== SRU Justification ================
+ Impact: nested containers fail to start
+ Reproduce: create a root owned container; install lxc and cgroup-lite;
create a container, and try to start it. Starting will fail if cgroup-lite is
running in the first level container without this patch.
+ Regression potential: should be low, it's possible that the regexp is simply
wrong for some cases.
